Carbonatites from the Southern Brazilian platform: I
2020
We present a comprehensive overview of the geochemical characteristics and evolution of the carbonatites from the southern Brazilian Platform (Paraná Basin). The carbonatites from different complexes display large compositional variability in terms of abundances of incompatible and rare earth elements. This is in agreement with an origin from heterogeneous lithospheric sources, as confirmed by isotopic data (see Speziale et al., this issue). The characteristic major and trace element abundances of these carbonatites present compelling evidence for invoking liquid unmixing as the main mechanism of their formation and evolution albeit few exceptions. We propose an evolutionary trend for the B…
English Validation of the Parental Socialization Scale—ESPA29
2017
Parenting styles have traditionally been studied following the classical two-dimensional orthogonal model of parental socialization. The Parental Socialization Scale ESPA29 is used to measure the four styles of parental socialization through the acceptance/involvement and strictness/imposition dimensions. The ESPA29 scale is a developmentally appropriate measure of parenting styles, which has been validated in several languages including Spanish, Italian, and Brazilian Portuguese. In this study, the English translation of the ESPA29 was evaluated. The objective of the work is to test the ESPA29’s structure of parenting practices with a United States sample measuring parenting practices usin…
The ambiguities of "granted constitutionalism" : a transatlantic debate (III)
2018
Our journey ends in Brazil. According to textbooks of constitutional history, this "periphery" country, recently independent, looked with envy at the European and North American constitutional novelties, not without trying to maintain its identity. Olhos na Europa, pés na América? Doubtless ; still it is necessary to measure the extent of this "Europe", admired in space as in time. The doctrine, criticizing the granted Constitution of 1824, qualified of nominal, had too long hid the reality, even the efficiency, of a constitutionalism in singular outlines, which involves both social and institutional engineering, thus not reducible to the modern constitutionalism. The political actors of Br…
Para uma cooperação da escuta e do movimento: Estudo intercultural sobre a percepção dos ritmos tradicionais do Xangô (Olinda, PE)
2010
Combining musical cognition and ethnomusicological approaches, this article seeks to verify if the capacity of recognizing and actually doing the appropriate beat of musical rhythms after listening to musical excerpts is influenced by the movements of the body. We would like to show to what extent variables like "musical competence" ("musicians" and "non-musicians") and "cultural origin" ("Brazilians" and "French") do influence such capacity. We try to answer these questions by applying an experimental protocol designed for that end. The musical rhythms used in the experiment are drawn from the musical and religious traditions of the xangô african-brazilian cult, as they are practiced in Ol…
Ceramique/metal component elaborated by flash sintering for ballistic protection
2012
This dissertation describes the synthesis of new components for ballistic protection with the assistance of flash sintering. Indeed, the objective is to associate two compounds showing very different sintering temperatures – such as alumina and aluminum, two reference materials for ballistic protection applications.The first synthesis method tested was the elaboration of a bi-material via the sintering of aluminump owder on alumina bulks. This study permitted to observe the formation of the alumina/aluminum bonding by scanning and transmission electron microscopy and to optimize the assembly parameters in order to obtain a bimaterials howing a strong interfacial cohesion. Adapted characteri…
O Brasil na rota das migrações internacionais qualificadas espanholas no século XXI
2018
In order to understand recent migration, it is crucial to analyze the migratory modalities such as skilled international migration to Brazil, especially considering the ongoing transnational economic processes and their effects on the corresponding societies. Therefore, this article seeks to understand how the migratory dynamics of highly skilled Spanish professionals to the country are established taking into account the theoretical contribution of the circulation of brains and the category of knowledge workers. For this purpose, information from Brazilian?s Ministry of Labor is used on labor authorizations, financial contributions and insertion in the formal market in Spain; as well as da…
Inhibition of Saccharomyces cerevisiae Pdr5p by a natural compound extracted from Brazilian Red Propolis
2011
Multidrug resistance of cancer cells and pathogenic microorganisms leading to the treatment failure of some forms of cancer or life-threatening bacterial or fungal infections is often caused by the overexpression of multidrug efflux pumps belonging to the ATP-binding cassette transporters superfamily. The multidrug resistance of fungal cells often involves the overexpression of efflux pumps belonging to the pleiotropic drug resistance (PDR) family of ABC transporters. Possibly the best-studied fungal PDR transporter is the multidrug resistance transporter Pdr5p of Saccharomyces cerevisiae. Some research groups have been searching for new inhibitors of these efflux pumps in order to alleviat…
Prevalence of oral mucosal lesions in a brazilian military police population.
2014
Background Data obtained from oral health surveys are very important for identifying disease-susceptible groups and for developing dental care and prevention programs. So, the purpose of the current article was to investigate the prevalence of oral mucosa lesions (OMLs) in a population of Brazilian police. Material and Methods Interviews and oral cavity examinations were performed on a sample of 395 police officers who were randomly selected by the calibrated researcher. The number of individuals was obtained by a sample calculation using the finite population correction. The diagnostic criteria were based on the WHO (1997) criteria and adapted to Brazilian surveys. Results In total, 8.61% …
Women fighters as agents of change: A Brazilian jiu jitsu case study from Finland
2015
Brazilian jiu jitsu (BJJ), a grappling system of combat, evolved from the teachings of a Japanese judoka who moved to Brazil in the 1920s. Focusing on ground fighting, BJJ is rapidly evolving into a combat sport with competitions taking place worldwide (Hogeveen and Hardes, 2014; Spencer, 2014). Unique to the BJJ culture is the way that the ‘secrets’ of the sport are transferred from expert to novice and from one club to the other. Clubs are organised into international ‘teams’, shaping global communities of practitioners that share techniques and philosophies. Unlike many other martial arts that insist on the traditional way of passing knowledge from one teacher to many students behind the…
Encuentro de saberes: Huellas de memoria pluriversa y descolonización de la Universidad contemporánea
2018
This paper studies the Encounter of Knowledge as a project that, by welcoming mestres and mestras of ancestral knowledge into universities, contributes to decolonize higher education, broadening its field of memory. Based on a systematization exercise, we established a theoretical dialogue with Bajtin and Bejamin. Based on the participation of four mestres -Lucely Pío, raicera del Cerrado, Mãe Lu and Tata Mutá Imé, religious leaders of Candomblé and the political leader and shaman Álvaro Tukano of the Tukano nation- we show how the project promotes in the contemporary Brazilian university a space of mnemic pluriversity, capable of activating diverse narrative planes (biographical, political…
